When using the x86 nightly build from Nov 15th, 2024 to run the DaCapo Spring benchmark, the JVM will livelock and throttle the CPU.

To reproduce, run java -XX:+FlightRecorder -jar dacapo-23.11-chopin.jar spring. The benchmark will successfully run without flight recorder enabled. Some other benchmarks, such as cassandra, appear to execute fine with JFR enabled.
